Windows 10 for IOT and Raspberry2

Setting up Windows 10 IoT Core on Raspberry Pi from a VM

Tip:

After a couple of troubles with a Windows 10 Preview VM I downloaded the Windows Assessment and Deployment Kit (ADK tools) for Windows 10 Preview on my Windows 7 machine and installed just the DISM Part.
Now I could run the DISM command on Windows 7. No need for Windows 10

HowTo



F() Macro

clock April 12, 2015 23:48 by author Administrator

explained on programming

Serial.println(F(“Hello World”));
Lcd.print(F(“W”));

The F() macro tells the compiler to leave this particular array in PROGMEM. Then when it is time to access it, one byte of the data is copied to RAM at a time. There’s a small performance overhead for this extra work. However, printing strings over Serial or to a LCD is a really slow process, so a few extra clock cycles really won’t matter.

Serial: Multi Digit Integers

void

setup()

{

Serial.begin(9600);

}

void

loop() {

char buffer[] = {' ',' ',' ',' ',' ',' ',' '}; // Receive up to 7 bytes

while (!Serial.available()); // Wait for characters

Serial.readBytesUntil('n', buffer, 7);

int incomingValue = atoi(buffer);

Serial.println(incomingValue);

}

void

setup()

{

Serial.begin(9600);

}

unsigned

int integerValue=0; // Max value is 65535

char

incomingByte;

void

loop()

{

if (Serial.available() > 0) { // something came across serial

integerValue = 0; // throw away previous integerValue

while(1) { // force into a loop until 'n' is received

incomingByte = Serial.read();

if (incomingByte == '\n') break; // exit the while(1), we're done receiving

if (incomingByte == -1) continue; // if no characters are in the buffer read() returns -1

integerValue *= 10; // shift left 1 decimal place

// convert ASCII to integer, add, and shift left 1 decimal place

integerValue = ((incomingByte - 48) + integerValue);

}

Serial.println(integerValue); // Do something with the value

}

}
